# Point

A point represents a position in space. In modern mathematics, space is represented using the cartesian coordinate system where there is an origin and the point is measured by its distance from the origin.

## One Dimension

In one dimension a point is measured terms its distance from the origin along the number line. For example, the point below below is represented as .

## Two Dimension

In two dimensions a point is measured terms its distance from the origin in the x-direction as well as its distance from the origin in the y-direction. For example, the point below is represented as .

## Three Dimension

In three dimensions a point is measured terms its distance from the origin in the x-direction, y-direction, and the z-direction. For example, the point below is represented as .
